我正在尝试使用valgrind memcheck调试我在Fortran中编写的MPI程序。但是，即使我调试最小的MPI程序，Memcheck也会在第一个MPI语句MPI_INIT（IERR）上报告错误。 如果我评论与MPI相关的陈述，则不会发生错误。
以下是我的最小工作，你可以帮助解决这个问题。
主文件：testMPI.for
PROGRAM testMPI
IMPLICIT NONE
CALL myMPI_ENV_INIT
CALL myMPI_ENV_FINISH
STOP
END PROGRAM
mympi_env_init.for ```
SUBROUTINE myMPI_ENV_INIT
USE MPI
IMPLICIT NONE
INTEGER IERR
CALL MPI_INIT(IERR)
RETURN
END
mympi_env_finish.for
SUBROUTINE myMPI_ENV_FINISH
USE MPI
IMPLICIT NONE
INTEGER IERR
CALL MPI_FINALIZE(IERR)
RETURN
END

==5294== Your program just tried to execute an instruction that Valgrind
==5294== did not recognise. There are two possible reasons for this.
==5294== 1. Your program has a bug and erroneously jumped to a non-code
==5294== location. If you are running Memcheck and you just saw a
==5294== warning about a bad jump, it's probably your program's fault.
==5294== 2. The instruction is legitimate but Valgrind doesn't handle it,
==5294== i.e. it's Valgrind's fault. If you think this is the case or
==5294== you are not sure, please let us know and we'll try to fix it.
==5294== Either way, Valgrind will now raise a SIGILL signal which will
==5294== probably kill your program.
Program received signal SIGILL: Illegal instruction.

虽然它报告MPI_INIT有一些错误。它认为它必须是我在配置或程序上的错误，而不是OpenMPI。
你能告诉我如何摆脱这个问题吗？
